The clinical and hemodynamic characteristics, perioperative and early postoperative results were studied in 38 patients with aortic valve prosthesis in order to determine the indications for surgical treatment in isolated aortic valvular disease. The basic factors determining the need for surgical treatment are: severity of the aortic lesion--stenosis and/or incompetence, degree of the harmful action of the aortic valvular disease on the left ventricle (clinical data for left ventricular failure; hypertrophy and dilatation--telediastolic volume greater than 300 ml/m2, telesystolic volume greater than or equal to 50 ml/m2; myocardial lesion; hemodynamic data for left ventricular dysfunction) and functional class of the patients. Most of the patients were with severe aortic incompetence and/or aortic stenosis and considerably diminished functional capacity. Only few patients had a low degree valvular lesion but they also showed some of the signs of its harmful action on the left ventricle.
为确定单纯主动脉瓣疾病的手术治疗指征，对38例主动脉瓣置换患者的临床和血流动力学特征、围手术期及术后早期结果进行了研究。决定手术治疗必要性的基本因素包括：主动脉病变的严重程度——狭窄和/或关闭不全、主动脉瓣疾病对左心室有害作用的程度（左心衰竭的临床资料；肥厚和扩张——舒张末期容积大于300 ml/m²，收缩末期容积大于或等于50 ml/m²；心肌病变；左心室功能障碍的血流动力学资料）以及患者的功能分级。大多数患者存在严重的主动脉瓣关闭不全和/或主动脉瓣狭窄，且功能能力明显下降。只有少数患者瓣膜病变程度较轻，但也表现出其对左心室有害作用的一些迹象。
